FIG. 4 is a diagram illustrating an example of a classification dictionary table according to the embodiment; As shown in FIG. 4, the classification dictionary table 22 includes information in which "specific information", "type", and "classification dictionary" are associated with each other.

"Specific information" is information indicating a category to be classified. In the example shown in FIG. 4, the "specific information" is stock prices, exchange rates, politics, and the like. Note that the "specific information" is not limited to the example shown in FIG. 4, and may be, for example, sports, real estate, examinations, used cars, cooking, travel, and the like.

“Type” is information indicating the type of index for classifying the information of the category specified by the specific information. In the example shown in FIG. 4, the "type" is trend, increase/decrease, instigation, and selling/buying when the specific information is stock price information or exchange rate information. be. Hereinafter, information indicating the type of index may be referred to as index type information.

The "classification dictionary" is generated for each set of specific information and index type information, and includes information in which words and index values are associated. The index value is an index value (score) for classifying the information of the category specified by the specific information. For example, in the category specified by the specific information, the index value approaches 1 as the word has positive information, and approaches -1 as the word has negative information.

In addition, for example, when the specific information is examination, the "classification dictionary" includes information in which index values and words related to examination are associated with each other. In this case, the index value approaches 1 for words that are more likely to appear on the test, and approaches -1 for words that are less likely to appear on the test.

Further, for example, when the specific information is cooking, the "classification dictionary" includes information in which index values and words relating to the quality of cooking are associated with each other. In this case, the index value approaches 1 for words that are more likely to mean delicious food, and approaches -1 for words that are more likely to mean less delicious food.

Also, when the specific information is politics, the "classification dictionary" includes information in which indexes and words related to politics are associated with each other. The political index is, for example, an index that indicates whether a party is pro-ruling or pro-opposition. In this case, for example, the index value approaches 1 as the word is closer to the ruling party, and approaches −1 as the word is closer to the opposition party. Ruling party-friendly words are terms that are likely to be used by ruling party politicians and people who are close to the ruling party, and opposition-friendly words are terms that are likely to be used by opposition politicians and people who are close to the opposition party. be.

In addition, when the specific information is sports, the "classification dictionary" includes information in which indices and words related to sports are associated with each other. The sports-related index is, for example, an index indicating whether the user is a baseball fan or a soccer fan.
